Northwest could eventually but not in the next five years because they are ordering more 757s inc the -300 and the 747-400.

The 727s are being replaced by the A320 and I think the A319 will replace some DC-9 routes as it already has been. I kind of think that the A318 will replace the smaller DC-9s. I doubt that Northwest will go for the 737 or the 717 because they will want fleet commonality and stick with Airbus for the small end of the fleet. Don't forget, Airbus has plans and models for the A316 and A317 also, but that doesn't mean they will fly.

If Northwest is really satisfied by the A330, they may replace the old 747-200s with A340s. Eventually (but not in the next 5 years) you may see the A380 replace the 744.

For the 757s? If Airbus would develop what could be known as the A322, that might a possible candidate.

USAirways was probably going to be the first U.S. airline using an all Airbus fleet of MORE than one type (Jet Blue only has 1 type- A320, so no one correct me on that).

But I doubt any of the other US majors will become all airbus, other than Northwest who has the best chance of doing so in perhaps the next ten years or so, but not anytime soon. It all depends on how much they like the A330s, that will make the difference.

I would doubt if someone says a carrier bigger than SR to go all-Airbus, because it would need one of 777-300 and 747, which Airbus hardly can replace with. 5 years remained for 380 to come out. And, don't forget, Airbus only makes jet airliners, and the smallest is 319, far bigger than 717.

I think a couple of other airlines in Europe could go all-Airbus fleet by 2006.

Iberia (IB) is a very good candidate to do this. Don't be surprised that IB buys a whole bunch more A320 Family planes in the next few years. This will allow IB to fly A320/A321's from their MIA mini-hub to destinations in Central America.

I won't be surprised if IB buys the A330-200/300 series and possibly the A340-500/600 series to serve BCN and MAD from around the world; people forget that Spain is now a major tourist destination, especially the Costa del Sol area.

RayChuang is right... Iberia's CEO stated some time ago that the iairline goal is to operate an all airbus fleet. The 757 are being gradually replaced by A321..While the MD80's and 87 will be replaced by A329 and 20's.
The company is also studyin type to replace their aging fleet of 747... (maybe this yaer?)
The 767's are actaully wet-leased from Air Europa and the A330 could fit on their fleet...

Could be IC. With the weay things are going, IC could well become an all-Airbus carrier.

At present IC operates 13 A300B4's, and 32 A320's. 12 ageing 737-200's are due for replacement, and the A318 is a hot favorite, since it shares fleet commonality with the A320's it already operates, and the A321's it plans to procure.

: IndianGuy - Actually, IC has only 30 A320s. 31 were delivered and 1 was written off at Bangalore in 1990. Also, IC operates 7 A300B2s, 4 A300B4s and h

26 767-332ER
: The A-321's were removed from service due to disputes with the pilots. IB has announced it would order more 757's.

: I was going to bring that up, but I couldn't remember the outcome...why did they switch to the 757 instead of just creating a new pilot scale for the
